LBRICATING DEVICE.

Application filed October 13, 1924, Serial No. 743,417. Renewedecember 6, 1926.

The present invention relates to new and useful improvements in lubricating devices, and it pertains moreparticularly to a device especially adapted for use in connection with 'force feed lubricators of the grease cup type.

It is one of the primary objects of the inrention to provide means whereby a forceV 'feed grease cup may be illed without removing it from its position relative to the mechanism which it is used to lubricate.

It is a further object of the invention to provide means capable of interposition between a lubricant receptacle and a mecha nism, such, for example, as a bearing to be luln'icated, which device will permit of lubrication ofthe bearing independent of the lubricant receptacle, a filling of the lubricant y receptacle independent of the bearing to be lubricated, or supplying lubricant directly and simultaneously to both the lubricant receptacle and the mechanism or bearing to be lubricated.

ItI is a further object of the invention to provide a device of this character which may be used in connection with grease cups as commonly manufactured without necessitating any structural or other change of the grease cup.

Vith the above and other objects in View reference is had to the accompanying drawings, in which- Figure 1 is a perspective View showing the manner in which a device constructed in accordance withthe present invention is used;

Fig. 2 is a longitudinal sectional view showing the manner in which a device constructed in accordance with the present invention is used and operated;

Fig. 3 is a detail longitudinal sectional view of a modified form of the invention.

Referring more specifically to the drawings and particularly to Fig. 1, the reference numeral 5 designates a shaft mounted in a bearing 6, said bearing having an internally screw-threaded lug 7 or the like, to which a grease cup is adapted to be secured. All of this is conventional construction.

The reference numeral 8 designates a.

shown in Figure 2, the lubricant receptacle comprises a shell 9. having a removable cover 10 and a discharge opening 11. Mounted Within the shell 9 there is a piston 13 having piston rod ll, which projects through an opening in the cover 10. Interposed between the cover 10 and the piston 16A v In carrying out the invention, a tubular member 20 is employed, such tubular member having an internally screw-threaded re-` i v cess 21 on one end and an externally threaded boss or projection 22 upon its other end.L u

20, there is an injecting nipple 23 of a conventional type. jecting nipple 23 and the externally thread- 'Projecting radially of the tubularfmember.

Interposed between the ined projection22, there is a valve 24 provided with a passage 25 extending therethrough.

The form of the invention shown in Figures 1 and 2, is adapted for use in connection with grease cups provided with a valve 30 similar to the valve 24 heretofore men tioned and is used in the following manner: The threaded extension 22 is engaged with the boss 7 of the bearing Within which .the grease cup would ordinarily be mounted. The threaded projecting portion of the grease cup is then engaged with the interiorly threaded recess 21 in order to mount the grease cup upon the bearing by means of the fitting. v

With the partsin the position shown in Fig. 2, when it is desired to replenish the supply of lubricant in the lubricant recep-` tacleit is only necessary to close the valve 24., place a pressure gun on the injecting nipple- 23 and force the lubricant under pressure through the injecting nipple 23', its only movement being in the direction of the lubricant receptacle. j

If a gun capable of producing sun'icient pressure to overcome the spring 15 is employed, the lubricant may be injected into the lubricant receptacle against the pressure of said springuntil the lubricant receptacle has been completely filled. t

If it is desired to lubricate the bearing direct without employing-the lubricant receptacle, it is only necessary to close the upper valve 30 and open the lower valve 24, in. which case the lubricant will be forced direct to the bearing.

25 y the 'present invention provides a lubricating lt sometimes happens that it is desirable lto cleanse they bearing, and in this case the upper valve 30v would be closed anda siiit able cleansing fluid forced through the fitting to the bearing to dislodge the grease or otherwise 'clean the bearing. After this has been done, the bearing may be again .lubricated in any of thekabove-des'cribed Ltion operates in the same manner as that described for 'the preferred forni.

From the foregoing it is 'apparent that device, by means o'f which grease cups may I be ieplenislied Without removal from their ii'iountings. The device further provides means for flushing or Washing outa bearingivithout removing the grease cup thereof, and, Aat the saine time, Withoutl affecting the lubricant Within thegrease cup; Y c Y From' the foregoingit isapparent that all of the objects of the present invention have been accomplished, and, further, it

should be understood that numerous modilications of structure might readily be resorted to Without in the least departing from thescope of the claims.

lhat is claimed is: y

l. A lubricating device comprising a lubricant receptacle adapted vforjattachment to a bearing to be lubricated, anda fitting adapted for interpositioii betvveen the bearingfto be lubricated and the lubricant receptacle, said fitting comprising a substantially tubular member, a lubricant injecting nipple carried thereby, and a plurality of valves, whereby lubricant may be forced siii'iultaneoi'isly or :selectively to the lubricant injecting nipple.

i2. A device of the character described comprising a fitting, means for attaching said fitting tov the bearing to be lubricated, means for attaching a force feed lubricator including a lubricant receptacle to the fitting, and ineens' carried bythe fitting for injecting a lubricant intothe lubricant receptacle and the bearing simultaneously, said means comprising `:i plurality of vvalves and any I'ii'ijecting nipple interposed with respect to said valves, said injecting nipple being carried vby the littiiig. j

3. For use in conjunction with a lubri 'eating' device, a litting :comprising a body having a passage therethrough, attachingl` means at each end .of the body, valve niembers carried ybv the vbody and each being operable for controlling said passage, and an injecting dev-ice connected to said body and being in communication .with said-passage.
